Key Features
- Dual decade ripple counter with independent divide-by-2 and divide-by-5 sections enables flexible decade, BCD, and frequency division configurations
- High-speed CMOS HC family provides fast propagation with wide 2 V to 6 V supply range and very low quiescent power consumption
- Two fully independent counter sections in a single package reduce component count for multi-decade frequency division designs
- Active-high master reset (MR) on each counter section allows synchronous or asynchronous system initialization
- 16-pin SOIC M96 tape-and-reel packaging is optimized for high-volume automated PCB assembly lines
Applications
The CD74HC390M96 is used in frequency division, decade counting, and digital clock generation circuits where two independent BCD or decade counter stages are required in a single package. It is commonly found in digital panel meters, frequency counters, event counters, and time-base generation circuits for industrial instruments and consumer electronics. The device's HC CMOS technology and wide voltage range also make it suitable for mixed 3.3 V/5 V designs in modern embedded systems requiring legacy TTL-compatible counting functions.

Frequently Asked Questions
How many counter sections does the CD74HC390M96 contain, and how are they organized?
The CD74HC390M96 contains two independent decade counter sections, each divided into a divide-by-2 stage and a divide-by-5 stage. By connecting the output of the divide-by-2 stage to the input of the divide-by-5 stage (or vice versa), you can form a standard BCD decade counter or a divide-by-10 frequency divider.
What is the operating supply voltage range of the CD74HC390M96?
As part of the HC CMOS family, the CD74HC390M96 operates from a supply voltage of 2 V to 6 V, making it compatible with both 3.3 V and 5 V digital systems. This wide range gives designers flexibility for use in mixed-voltage and battery-operated systems.
What does the M96 suffix on the CD74HC390M96 indicate?
The M96 suffix indicates the device is provided in the standard 16-pin SOIC (Small Outline IC) package on a 96-unit tape and reel, which is suitable for automated surface-mount assembly. This packaging is ideal for high-volume production environments using pick-and-place equipment.
Does the CD74HC390M96 support a reset function?
Yes, each decade counter section includes an active-high master reset (MR) input that asynchronously clears all counter outputs to zero when asserted high. This allows the system to initialize or synchronize the counters at any time, independent of the clock input.
What are typical applications for the CD74HC390M96?
Typical applications include frequency division in digital clocks and timers, decade counting in display drivers, event counting in industrial equipment, BCD generation for seven-segment display interfacing, and prescaler circuits in communication systems. The dual independent sections make it especially efficient for cascaded multi-decade counting designs.
